Smokescreen was a member of the Elite Guard, a select corps of Autobots, and is a fiery warrior who is ready to combat his enemies fair and square. His current vehicle mode is one he chose for the sake of his mission, but it is considered a problem for being too conspicuous. He is equipped with a variety of weaponry, utilizing such things as magnetic smoke emitted from his muffler. On Cybertron, he fulfilled the vital role of bodyguard to the Autobot mentor Alpha Trion. His reasons for suddenly appearing on Earth are still a mystery.
